Unplastered roof construction. As per AISC for roof beams without plaster subjected to only live loads, maximum deflection is L/240.Since L=20 feet=240 inches.Therefore maximum allowable deflection is 1 inch.
For plastered roof construction the maximum allowable deflection is L/360.
Add Answer to:

a simply supported beam shown has a span length of 16 ft. the
beam is laoded with to concentrated service live loads of 40 kips
and 80 kips as shown. if lateral support is provided only at both
ends, select the lightest w section of A992 steel that can carry
these applied loads. neglect the weight of the beam.

Check the adequacy of a W18X35 for a beam (the beam in the vertical direction in the plan) in a floor framing system in terms of 1) bending strength; 2) shear strength and 3) deflection. The beams support a 4-inch-thick reinforced concreted floor slab (with a density of 150 lbs/ft?). Besides the weight of the structure, loads consist of a uniform live load of 80 psf and moveable partitions (with a uniformly distributed load of 20 psf of floor surface)....

The walls are 10 in. thick with an allowable compressive stress of 300 psi (pounds per square inch). A 3 ft wide vertical strip of wall currently supports both a roof load of 1.5 kips and 11 floor loads of 2.0 kips per floor. Each story is 12 ft tall from floor to floor. The density of the masonry wall is 130 pcf (pounds per cubic foot). What is the maximum total force support by a 3ft wall segment for...

m 3: (20 points) Design the stirrup spacing for the beam shown below. Change your design between Zones 1, 2, and 3 of the beam length, using a uniform spacing in each zone. Ignore the self-weight of the beam. Loads on the beam are service loads so load factors must be applied according to ACI 318 (subscripts "d" and T" denote dead and live loads, respectively). Material strengths are fe 4,0oo psi and fy 60,000 psi. The total factored shear...

Assume that the floor between Beams B7 and B8 is supported
directly by these two beams only (not by Girders G2 and G3). Beam
B7 has a self-weight of 30 plf. The floor slab consists of a
4-in.-thick, normal-weight, reinforced concrete slab (unit weight =
150 pcf). An additional floor dead load of 15 psf is specified to
account for the weight of suspended utilities and fixtures. As an
exterior beam, B7 must also support one...

1. You are given a simply supported, uniformly loaded beam (W14x26), 20-ft long which is laterally supported and which carries a dead load of 0.5kips/ft and a live load of 1.5 kips/ft. You are to compute the maximum live load deflection and compare it with the maximum allowable live load deflection of L/360. If your live load deflection is larger than the allowable live load deflection, determine the magnitude of the moment of inertia needed...

Two similar beams are delivered to a construction site. Each beam is a hollow box beam, constructed of A36 structural steel, (E=29.0 x 106 psi, density of 490 lbm/ft?), each beam having outside dimensions of 16" base and 18" height, 18 feet long. Beam A has top and bottom wall thicknesses of 0.5" and side wall thickness of 0.375". Beam B has top and bottom wall thicknesses of 0.4375" and side wall thickness of 0.3125".

Steel foot bridge. The main beams are W10X12 A36 steel. Each beam are 36 feet long. Each beam is to support decking 18 in wide for the length of the beam (36 feet). Deck material places a 50 pounds per sq ft distributed load on the beam. In the center of the beam needs to support a 1200 lb point load. What are the loads on the beam and the safety factor?
a simply supported beam shown has a span length of 16 ft. the
beam is laoded with to concentrated service live loads of 40 kips
and 80 kips as shown. if lateral support is provided only at both
ends, select the lightest w section of A992 steel that can carry
these applied loads. neglect the weight of the beam.
